About InsecureBank
InsecureBank is a web application created using Django, designed to showcase the potential danger of SQL Injection attacks. An application becomes vulnerable to such attacks when it fails to properly sanitize submitted data through its forms. Sanitization ensures that only the expected data types and values are allowed into the system, but without it, the application is unable to differentiate between valid and malicious data.
What is a SQL Injection Attack?
SQL Injection is a type of security attack where an attacker injects malicious SQL code into the application, often via input fields. This can trick the application into executing unintended SQL commands and compromising the database, leading to data loss, data breaches, and even complete takeover of the system.
How Does a SQL Injection attack work?
The attacker can use SQL Injection to extract sensitive data such as usernames, passwords, and credit card information or modify the database's contents, changing records, and inserting new data. This attack can occur when developers do not properly validate user inputs and trust that the data sent to the server is correct.
Conclusion
Always sanitize your data! By ensuring all data inputs are properly sanitized before they are processed by the application, we can guard against this type of vulnerability.
